2.4.3 Enabling Gratuitous ARP
Configuration Effect

Configuration Steps

incorrect gateway MAC address in case of ARP spoofing.
 Enable gratuitous ARP in interface configuration mode.
Verification
Run the show running-config interface <name> command to check whether the configuration is successful.
